Impact of Intraoperative Branch Embolization for Type 2 Endoleak Prevention During Endovascular Abdominal Aortic Repair.

Background: Endovascular abdominal aortic repair (EVAR) has a significantly higher revision rate than open repair, primarily due to type 2 endoleak (2EL). Although 2ELs are considered benign, late open conversion (LOC) due to the expansion of the aneurysm diameter of the 2EL is a concern in the mid- and long-term. In this study, we investigated the impact of embolization of the inferior mesenteric artery (IMA) or lumbar artery (LA) at the time of the initial EVAR and its long-term outcomes.

Extensive aortic replacement including aortic arch for a mega aorta with chronic aortic dissection via posterolateral thoracotomy.

Background: Mega-aortic syndrome including aortic arch and descending aortic aneurysm is a challenging surgical case. Because the aorta continuously dilates, creating the distal anastomosis sites becomes an issue. Despite the developments in endovascular techniques including frozen elephant trunk, in the case of mega-aortic syndrome or mycotic aneurysm, extensive surgical repair is still a strong armamentarium.

Improvement of image quality for bright-blood image in VISIBLE (volume isotropic simultaneous interleaved bright- and black-blood examination) by using k-space reordering and startup echoes.

Purpose: A volume isotropic simultaneous interleaved bright- and black-blood examination (VISIBLE) can simultaneously acquire images with suppressed vascular signals (black-blood images) and images without suppression (bright-blood images). We aimed to improve of the bright-blood images by adjusting the k-space filling and using startup echo.

Methods: The k-space arrangement of bright-blood images in the conventional VISIBLE followed a low-to-high frequency order, whereas that in the proposed VISIBLE sequence was in the reversed order, and a startup echo was added.

Amide proton transfer-weighted imaging with a short acquisition time based on a self B0 correction using the turbo spin echo-Dixon method: A phantom study.

Purpose: Conventional amide proton transfer (APT)-weighted imaging requires a chemical exchange saturation transfer (CEST) sequence with multiple saturation frequency offsets and a B0 correction sequence, plus a long acquisition time that can be reduced by applying the conventional method using CEST images with seven radiation pulses (i.e., the seven-points method).

Exploration of appropriate media to influence sustainable on-site sanitation choices in Sri Lanka- visualization with still images or a video.

Pit latrines are the most common form of improved sanitation in many rapidly developing countries. However, they cause the highest amount of groundwater pollution among on-site sanitation (OSS) facilities. Many households in developing countries use groundwater as their main or sub-source, and pit latrines are not a sustainable solution.
